antifreeze leak

[JOEYBELL321]

I replaced the gaskets on my 165 mercruiser thinkink one of them was leaking.Ithen found the leak was coming from a factory hole in the timing chain/ ciculating pump housing that seems to be there so coolant doesnt go into the timing chain.<br />The leak starts as soon as I pour water into the reservoir.

Re: antifreeze leak

the seals are bad on the end of the camshaft just behind the impeller for the circ.pump.you will probably need repair{speedy}sleeves to put on the areas where the seals ride because the seals have worn a groove in the shaft.
